From NIC to Lan On Motherboard (LOM)
1. LOM removes the cost barrier to adopt 10G On servers. 2. Server vendors require LOM to be backward compa>ble,hence LOMs should support: Interoperate with 100/1000/10000 switches Support RJ45 cabling infrastructure 3. 10GBASE–‐T meets these requirements and is the PHY of choice for 10G LOM ENPAK DWDM transceiver
